(o1.;5sw1s 5. j g' 1 I This invent-ion relates to a harvesting machine 7 and, more particularly, to improvements in means for conveying harvested material from the harvesting means to a point where such -material may be deposited on the ground or otherwise reeeived. i e

In the usual type of harvester of one particular class towhioh the invention is especially adapted, a main frame is carried inappropriate ground wheels and means are provided for adjusting the 110 'main frame vertically so that the harvesting means, which are carried by the frame, may cut cropsat different heights. I The ordinary harvesting means operates in co junction with a conventional platform or apron conveyor which re- .ceives out crops ormaterial from the harvesting meansfor conveying of such material to asecond elevator or conveyor which, in turn, oonveysgor delivers the .cut material to a point remote irom the harvesting means. Tllhe delivery of suohgma- 2O terial may bemade directly .upon the stubble at -one'side' of the harvester or may be otherwise received in some appropriate receptacle; .It has been found in prior machines of the type referred to that the arrangement of the elevator or non-P veyor is such as to besubject to the disadvantage that its delivery .end .iswdisposed at different heights accordingto the adjustment of the main vframelasla whole. Thisvis disadvantageous, he-

cause the point of .deliverythen varies with re aspect to the final .disposition'on the stubble 101 other receptacle. 1 a r =It is accordingly the principal obiect {of the present invention to provide aeonveying- .or ele- .vating machine so mounted .with r-respect to the" main firame. asto haveits delivery end maintained substantially at a .uniiorm positioninrespecttve of addustment ofthe main frame.

An -.-important object of the inventions 3151 to the ground supportso'thatithemain frame, which nrdinarilysadjustable-with respect :to the. ground :support, is also adjustable with respect-to the oo vey means. l

' not shown, whichjserves to rotate the shaft for .mount'thedelivery end of the conveyingimeans on A5 ft-is another object of the'invention zto provide :means for :mounting the conveying means for swinging movement through an. arc which .doeszndt substantially varyfthe height of the-delivery rend :of the (conveyor. o

' Still another :object is :to provide ;a delivery chutelso'. arranged with respect ,to the .-conveying means as to have :itsdelivery lend alsotmaintainalole ata substantially uniform height.

And :still another object is 'to provide :means 56 V whereby-the delivery end oi thechute maybe adjusted if desired.

A complete understanding of the foregoing and other desirable objects and teaturesof the in:

vention may be had from the tollowing detailed 7 description and accompany-mg sheetsofdrawings illustrating a preferred embodiment of the invention. 1 T I in the draWi-rigs- Figure l is a side elevational view of a harvesting machine embodying the invention, the final delivery chute being omitted;

The draft frame may be connected in. any suitable manner with the draw-bar of g a tractor, not shown, as generally indicated at 26. Adjacent its forward end, the draft frame 23 carries supporting structure 21 serving to mount a gear casing 23. This casing is provided with suitable gearing and provides means whereby power may be transerably by means consisting of a pair of adjustable links 51.

As previously described, the gearin in the gear casing 28 drives the upper roller shaft of the conveyer 38. The shaft 34 carries for rotation therewith a gear 58, which meshes with a gear 53 on the shaft 46 of the upper roller 45 of the upper elevator 44. The shaft 34further carries a driving sprocket 63, about which is-traineda drive chain 6|. The lower end of thechain is trained about a drive sprocket 62 carried on the shaft 49. The shaft 40 enters a gear-box 63 containing appropriate bevel gearing, not shown, by means As best shown in Figure 2; the 'frontfra'me i2,

of the main frame It i provided with upstanding supporting structure generally indicated at 35. This structure comprises avertical plate 36'and a brace bar 36a. The plate -is-rigidly secured 'toithe forward ,end' of a longitudinally extending,

tubular support 31, the rearward and lower end of'this support'being connected to the rear end of the main-frame'lO.

The conveying or elevating" means 'isgenerally indicated at 38. This means comprises a'pairof longitudinally spaced, upwardly inclined sheets 39 pivoted at their'lower ends on a longitudinal axis on a longitudinally extending pivot about a shaft 46. The upper ends ofthe sheets 39 carry-therebetween' a drivin roller 4! about which is trainedan elevator-or conveyercanvas 42. The lower. end of the canvas is trained about alower roller 43. The j conveyer means further includes an upper elevator canvas 44 trained about an upper roller 45-on a shaft 46 and: alowerroller 41.-

.A- transversely running apron-or platform conveyer 48 operates rearwardlyof the'cutting mechand is adaptedto receive cut material from the One end of the platform apron 48 is trained abouta roller 43 of the conveyer -38-. -Theelevator 42 and 44 0f: the conveyer 38 thus operate to pick up material from the platform 48 for the delivery of suchmaterialin the usual manner;

As previously stated, the lower end of the conveyer unit 38 is pivoted on the longitudinally extendingshaft49. The conveyer thus has-move- ,ment-with-respect to the remainder of the main frame structure. The upper end of the conveyer is located above the ground wheel l4 andis supported inthatpcsitionbymeans mounted on a part of the ground wheel. Thismeans comprises a bearing orsuppo'rt 50-carried on the axle I5 of .the wheel. I Thisbearing haspivotally connected per end on the conveyer 38, preferably by means of the pivot 52 previouslydescribed. This chute consists'of a pairof side sheets 54 and a bottom sheet 55 which extends at its lower end trans-- versely o-f-the outermost portion of the main frame, as indicated at 56.'- The lower end of the chute 53 is supportedon-themain frame I 0-, prefof which power may be transmitted to other parts of-the harvesting machine. A drive shaft 64 extends transversely from the gear-box 63 toward the ground support 14, adjacent which the main frame l0 carries agear-box 65. Suitable gearing, not shown, within this gear-box transmits power to-a longitudinally extending stub shaft 66 on the outer; end of which is mounted afly-wheel 61. A

A shaft it extends vertically from the gearbox 63 and isconnected b a universal joint H to another vertical shaft 12.1 This shaft parallels :oiie leg of a vertically extending U-shaped support T'Scarried' at its lower end at 140m the supporting structure 35 of the main frame If). This U.-frame carries upportinglst'ructure generally indicated at-Mfor the mounting of a reel shaft 15.. This reel. cooperates in the usual manner with. the harvesting mechanism. 3 The shaft 15 carri'es'at its stubbleward end a large bevel gear 16,.whichmeshes with a,bevel pinion H on the vertical. shaft '72.. In thismanner the reel shaft 1,51is driven through the gear casin .63 from the upper rollenshaft 34 of the elevator 33. As has been previously set, forth, the elevating and cutflting mechanisms are also driven from this shaft.

drivesa sprocket 8 0 on the roller 49 of the platform"ap ron 48;. K t ma ine rd n 7 cedure'is followed. By means of the worm-wheel and rack; and pinionrnechanism previously described, the height of thecutting mechanism may be adjusted withrespect to the ground. In Figure 2, the main frame is lowered .to a positionin which thecutting mechanism operates ata comparatively low height; It will be noted that the "delivery end 56 ofthe delivery chute 53 is dis posed ataheight above the ground at which'de- "livery offtheharvested material may be convenie'ntly made on'top of standing stubble.

As-shown in Figure3, the mainframe has been moved vertically upwardly. so that 'the cutting -mechanism is disposed at substantially its maxi- .heightaboveth'e ground. 'Because of the novel's-supporting arrangement of .the conveyer 38 and deliverylchute 53, .the delivery. ends :.of
